`i Specification of Letters Patent No. 5,318, dated October 2., i847.

reference being had tothe accompanying drawings, making part of this' specification,V

in which- Figure l is a front elevation; Fig. 2, a

vertical section through the loom from frontto back; Fig. 3, a section showing the back' part of the frame inside together with the warp beam and apparatus for regulating theL tension of the warp.

The same letters indicate like the figures.

- The frame of my loom is constructed like those in common use; on the crankshaft (C) there is a driving pinion (b) and the usualv pulleys; the lat-he (c) is constructed similar to those of ordinary looms with the picker staif passing up through the' bottom of the box; the shaft (d) on which the swords of the lathe are hung revolvers being driven Lby the pinion of the crank shaft, this pinion (b) is connected with a spur wheel (e) on the shaft (CZ) of twice its diameter by an intermediate wheel (f) of the same size as wheel (e), by this arrangement the shaft (el) is turned once around during two revolutions of the. crank shaft. On each end of shaft (CZ) which projects a sufficient distance beyond the frame there is a side cam or projecting screw thread (gi) this is clearly represented in Fig. l, it makes but one turn around the shaft and the gain is just suiiicient to draw back the picker staff the two ends of this screw thread are connected by a bar shown on the right hand worm; thev end of the screw thread falls off a little at (A) so as to allow the picker to move forward suiiiciently to rest firmly againstthe end of the shuttle before it is thrown. The

picker bears at its lower end against the inside of the worm, its fulcrumbeing at (h) on an arm that projects .from the side of the sword of the lathe for that purpose; above this fulcrum (L) a spring strap of metallic or other suitable india rubber is lixed around: the staff and extends up to a ring on a bolt that passes through the sword and has a parts in all nut onthe opposite side whichican be used for adjusting the tension of thejspri'ng. The

upper end of the picker staifwithiny the shuttle'box hasfa socket yin it (see, Fighe) piece of leather is driven to form invvhich a the picker.

.In this construction of parts willnbe, perceived that the picker staff yis gradually j tion ofthe shaft (d) and is then suddenly carried back during the whole of therevoluforced forward by the spring E0 throw the shuttle; this obviates the necessity of a sudden blow from a cam as in ordinary 4looms j and the consequent wear and lo'ss of-power T attendant thereon.k The shuttle' boxes are: s made of one casting having lugs or ears cast onto the four `corners that come down Y over thesidesof vthe race beamjand have common woodscrews put through them' to fasten vthe boxto its place3this-- forms ak cheap Landsubstantialgxture easily fitted v up and applied;.j

j The'harnessfraine (Z) harnessroll i are of ordinary' construction, but the harness is connected with a shaft (fm) below and parallelwith the roll. This shaft has its bearings in the` lower ends of the goose necks of the lharness frame and has on the righthand end, or that on which the gearing above described is placed a small inion l (n) below this shaft there is a stud 0) on'` 'which a yoke or U formed lever (p) is hung near the bend with the two arms projecting upon each side of an eccentric (g) that is fixed on a vshort shaft (1") on which the wheel (f) above named is placed, this has one revolution -to two of the crank shaft.

The eccentric' causes the yoke to vibrate each way during its revolution. On the upper end of the forward arm of the yoke .(p)

there is a segment rack (20') that gears 'into the pinion (n) on the shaft (m) and causes said, shaft to turn back :and forth at each u vibration of the yoke, thus 'regularly springing the harness upand down. without any,A

sudden action which is lfound in the ordinary n j cam looms so destructive to the harness and" i warp and which wastes so much power.

My movement of theharness is regular and easy and with it the slackest twisted or loaf most tender warp can be woven into cloth without danger of constantly breaking down-fa thing of the greatest importance in goods, on'tl weaving soft flannels and other which a nap is tobe raised.

Directly in the rear` of theeccentric there.v

tends back to the rear of the frame under` the yarn beam on the front end of this shaft (s) there is a ratchetwheel (8') into which a dog (u) Works, this dog is struck by a projection (u) on the side of wheel (f) at every revolution which causes the shaft to revolve; on the rear end of this shaft (s) there Vis a worm wheelthat works into a pinion (42') on a'shaft (o) placed above and at right angles to the shaft (s) the bearing of the shaft ('v) nearest the pinion is permanent, that at theother end allows the shaft to move up and down; a band (fw) is attached to this shaft justinside of the pinion that passes up and Vwinds aroundV the yarn beam (t) and thence down to theV frame,

this is for the purpose of tension of the warp. i

A screw is cut on the shaft (fv) on which a hook with a female screw cut in it ts and han'gsgto this hook a weight' (y) is suspended and is gradually drawn as" the shaft ismade to revolve from theinner end up regulating the toward the fulcrum or outer bearing. By.y

this arrangement the greatest accuracyof tension of warp is preserved throughout the whole process vof weaving it into cloth.

What I claim as my invention and desire to secure by Letters Patent is- 1. The method of working the picker v Vstantial picker is made.

stavesas herein described by means of a worm so constructed as to drawback the picker staves gradually during the. Whole revolution, by comingffinto direct contact with the staves; and throwing the shuttle by means of springs constructed and arranged substantially in the manner and for the purpose set forth.

2. I also claim constructing the picker" in the manner described by forming a metal socket on the end of the picker staff andinserting therein a piece ofA leather or other suitable materialby which a cheap and sub- 3. I yclaim the apparatus for moving the harness Vconsisting ofv a bottom roller to which the harness is attachedwhich is turned by a segment rack moved by an eccentric on the second shaft,` substantially in the manner described, by which a great saving is made in the harness and warp and the ordinary cam shaft is dispensed with.

4. I claim regulating the tension lof the warp inthe manner substantially as described, causing the weight gradually to approach the fulcrum of the shaft by revolving said shaft or lever on which a screw is cut for that purpose in the manner set forth.
